Patented Feb. 19,v 1952 CERTIFYING DEVICE FOR CASH REGISTERS Biagio Beria, Turin, Italy Application February 25, 1948, Serial No. 10,667 In Italy January 14, 1943 section 1, Public Law 690, August s, 1946 Patent expires January 14, 1963 s claims. (c1. i- 93) This invention relates to cash registers, more particularly to apparatus for the double certification of bills, invoices and the like.

According to this invention the sheet feeding mechanism is arranged to vary the distance between the two impressions without replacing any part of the apparatus, merely by properly adjusting a movable part on a rotating cam.

I'he mechanism includes a slidable carriage to which the sheet is secured by means of a gripping member operated by a cam through a system of levers, after the sheet has been placed on the slidable carriage. `During the movement of the carriage, the printing hammer is raised twice to print on the sheet the indications carried by the printing rollers.

'I'he cam is of a prole composed of two diametrically opposed arcs of circles of different diameters, one end of the arc of smaller diameter merging into the corresponding end ofthe arc of greater diameter through a step and an arc of variable curvature, while the other end of the arc of smaller diameter merges into the corresponding end of the arc of greater diameter through an arc of variable curvature.

By the above-mentioned arrangement, when the invoice, bill or the like is slipped through a suitable aperture until it comes by its edge against the stop secured on the slidable carriage, and the machine is actuated at first the cam step comes into action and brings the gripping member into Contact with the carriage in order to retain the sheet, next the printing hammer is operated, to carry out on the bill or the like the desired registration, as the bill is held by the member retaining it to the carriage as mentioned above. On further rotation of the cam, the sheet is moved forward with the carriage toward the outside over the full period in which the operating lever runs from the profile of a smaller diameter to that of a greater diameter of the cam, whereupon the carriage stands still over the full time during which the lever is acted upon by the arc of a larger diameter. During this period the printing hammer comes into action for the second time and repeats the registration on another point on the bill or the like, the carriage is then returned by a spring to its initial position, while the sheet is momentarily retained by the printing hammer which remains a short time in its printing position.

The accompanying drawing shows by way of example a construction of the object of this invention.

Fig. 1 is a longitudinal sectional View of the certifying device of the present invention on a plane parallel with the sliding direction of the carriage.

Fig. 2 is a plan view of the device, and

Fig. 3 is a detail elevational view of an actuating cam of the device.

Referring to the drawing, I denotes the table supporting the bill, invoice or the like, which is introduced"""into the machine through a suitable slit cut in the casing of the machine. A T- shaped carriage 2 is mounted over said plane in ak suitable spaced relationship and is guided in its movement by lateral guides 3 secured by screws to the table I.

A flange 4 is attached to the end of the carriage shank, and has anchored thereto the end of a spiral spring 5 which is Wound about a roller Ii and is connected at its other end to a pivot 'i lsecured to the casing 8 of the conventional roller mechanism feeding the ribbon by which the slips are issued by the usual manner by the cash register.

The flange 4 has xedly connected thereto a tab 9 having pivoted thereto a rocking arm II) carrying at its free end a gripping tongue II adapted to cooperate with the carriage head for gripping the sheet to be certied that has been introduced into the machine. In its inoperative position the tongue I I is underneath the supporting table, in order to admit free introduction of the sheet.

The rocking arm I0 extending downwardly through slits cut in the carriage and in the supporting table, is provided with a tooth I2 coacting with a roller I2 xed to the end of a lever I 3 pivoted to a xed pivot 50. The other end oi the lever has xed thereto a roller I3 which is acted upon by a cam I4 keyed on the driving shaft I5. The prole of said cam comprises an arc of a circle I6 having diametrically opposed thereto an arc of a circle I'I larger in diameter. One end of the arc I6 merges into the corresponding end of the arc II through a step I8 andan arc of varying curvature I8', while the other end of the arc I6 merges into the corresponding end of the arc Il through an arc I9 of varying curvature.

The casing 20 is arranged over the outer end of the supporting plane I and has mounted therein the printing rollers 2| actuated in the usual manner by the mechanism of the cash register.

A wide slot 23 is cut in the supporting surface at the pad of the printing hammer which effects printing therethrough.

The printing hammer 33 is actuated in the following manner: the driving shaft I5 has secured thereto a second cam 30, which is provided with two teeth 3|, 32. The printing hammer 33 is xed to a lever 22 pivoted on a pivot 34 xed to the frame of the apparatus. A second lever 35 is secured to the lever 22, said lever ending by a roller 36. The spring 31, having one Aend 'fixed to the lever 35 and its other end fixed to a point on the frame, constantly keeps the roller 36 in contact with the cam 30. One each turn of the driving shaft I5, the cam 30 raises twice the printing hammer 33, the teeth 3I-32 .being so arranged that the hammer is raised when the roller I3 contacts with cam I4 on Athe arc of fa circle I6 or I1, respectively, that is, when the slidable carriage does not perform any relative movement with respect to the table "I In order to adjust the distance between the two certifications on the sheet, the cam I4 is com-- prised of two parts a, b connected together by means of slits 26 and clamping screws 21.

It will be obvious that by the above described arrangement, when the part b is moved outward as shown in Figure 3, Athe distance between both certifications is increased.

A stop 24 is provided on the carriage and projects downwardly into the clearance between the carriage and bearing table and serves for limiting the introduction of the sheet by the desired extent. The stop 24- is adjustably mounted by means Yof a pin-and-pivot fastening, in order to vary the position of both certifications simultaneously on the sheet.

The mechanism operates in the following manner.

The invoice, bill or the like is introduced into the machine, till its leading edge is brought against the stop 24 .and the machine is set into action. On rotation `of the cam I4 in the direction shown by the arrow, the roller I3' at the end of the lever I3 runs over .the step I8 on the cam and the arm I is lifted to retain the sheet between the carriage 2 and gripping tongue I I.

The lever 22 is then actuated by the projection 32 on the cam .30 through the lever 35 and roller 36 and shammer 33 effects the iirst printing step` On further rotation of the driving shaft I5, the hammer 33 is lowered by spring 31 and the carriage is moved `forward to expel the bill or the like over a certain distance, which is determined by the distance of the axis of the driving shaft I of the arcs of circles I6 and I1. As the arc I1 passes over the roller I3', the projection 3I on the cam performs the second printing operation through the hammer 33 over levers 35 and 22 and roller 3B.

The carriage 2 is in turn returned to its initial position by the spring 5.

Obviously, the form and constructional details may be varied in whatever manner to suit practical requirements `without departing from the scope of this application.
